Android kann nicht zur vorherigen Aktivität zurückkehren

Question

Ich arbeite im Nachrichten-Feed wie Aktivität, die Listenansicht enthalten. Die Listenansicht enthält mehrere Videos. Wenn ich auf die Videoansicht klicke, öffne ich eine andere Aktivität und spiele das Video im Vollbildmodus ab. Wenn ich zurück drücke, kann die Aktivität nicht zu vorherigen Aktivitäten verschoben werden, die Listview enthalten.

wenn i-Taste gedrückt wieder die gleiche Aktivität lädt sie nicht zu früheren Tätigkeit geht

Auch versuche ich

finish() 
moveTaskToBack(true); 

aber keinen Gebrauch ....

Folgende Codes werden verwendet:

ListviewActivity

Intent intent = new Intent(MainActivity.this, VideoActivity.class); 
intent.putExtra("VideoURL", MY_VIDEO_URL); 
startActivity(intent); 

VideoActivity

public class VideoActivity extends Activity { 

VideoView videoSurface; 
ProgressDialog pDialog; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.video_activity); 

    ToastMsg.displayShortToastMsg("CREATE"); 
    String videoUrl = getIntent().getStringExtra("VideoURL"); 

    pDialog = new ProgressDialog(VideoActivity.this); 
    pDialog.setMessage("Loading Please Wait..."); 
    pDialog.setIndeterminate(false); 
    pDialog.setCancelable(false); 
    pDialog.show(); 

    videoSurface = (VideoView) findViewById(R.id.videoSurface); 

    try { 
     // Start the MediaController 
     MediaController mediacontroller = new MediaController(
       VideoActivity.this); 
     mediacontroller.setAnchorView(videoSurface); 
     // Get the URL from String VideoURL 
     Uri video = Uri.parse(videoUrl); 
     videoSurface.setMediaController(mediacontroller); 
     videoSurface.setVideoURI(video); 

    } catch (Exception e) { 
     Log.e("Error", e.getMessage()); 
     e.printStackTrace(); 
    } 

    videoSurface.requestFocus(); 
    videoSurface.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
     // Close the progress bar and play the video 
     public void onPrepared(MediaPlayer mp) { 
      pDialog.dismiss(); 
      videoSurface.start(); 
     } 
    }); 
} 

@Override 
public void onBackPressed() { 
    super.onBackPressed(); 
    } 
}

Answer 1

folgende in manifeste mit dem Hinzufügen der Try.

<activity 
    android:name=". VideoActivity" 
    android:parentActivityName=".MainActivity"> 
    <meta-data 
    android:name="android.support.PARENT_ACTIVITY" 
    android:value=".MainActivity"/> 
</activity> 

Answer 2

Versuchen Sie folgendes: -

videoSurface.setMediaController(new MediaController(this){ 
    public boolean dispatchKeyEvent(KeyEvent event){ 

     if (event.getKeyCode() == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) 
      finish(); 
     return super.dispatchKeyEvent(event); 
    } 
}); 

Answer 3

Bitte überprüfen Sie, ob Sie Meta-Daten

<activity 
     android:name=".VideoActivity"> 
     <meta-data 
      android:name="android.support.PARENT_ACTIVITY" 
      android:value="YOUR_PAKAGE_NAME.VideoListActivity" /> 
    </activity> 

für Ihre VideoActivity in Manifest-Datei hinzugefügt haben.

Answer 4

VideoView kann verbraucht die ACTION_DOWN Ereignis und damit KEYCODE_BACK feuert nie in die dispatchKeyEvent().

Von Context

Verwendung dieser Code in Ihrer Aktivität:

videoSurface.setMediaController(new MediaController(this){ 
    public boolean dispatchKeyEvent(KeyEvent event) 
    { 
     if (event.getKeyCode() == KeyEvent.KEYCODE_BACK) 
      ((Activity) getContext()).finish(); //finish current activity 

     return super.dispatchKeyEvent(event); 
    } 
});
